Polymer systems are hugely complicated, in part due to their semi-crystalline structure. Indeed, it is worth discussing the role of crystallinity in the piezoelectric behaviour of polymers. There are conflicting theories regarding the role of crystallinity in the piezoelectric behaviour of polymers.
Webb22 nov. 2004 · A theory of oriented crystallization in elongated polymers having network structures (e.g., in vulcanized rubber) is developed through the application of statistical mechanical procedures similar to those employed in rubber elasticity theory. Expressions are derived which, within the limitation imposed by the simplifying assumptions, relate … WebbAbstract Poly( l -lactide- co -e-caprolactone) [P(LLA-CL)] (82/18) film was made amorphous and a comparative study on the effects of rapid crystallization on the physical properties and mechanical properties of the film during hydrolytic degradation in phosphate-buffered solution and storage in the absence of water at 37 °C was carried out.
